The conducted an extensive survey analysis across 135 organizations in Serbia, assessing their readiness current practices...

This paper presents a methodology for applying the Lean Six Sigma method on educational process. After defining defects that have negative influence final quality evaluation of higher education and how these can be remedied, Pareto analysis is done, used establishing vital minority exams are critical examination faculty. The next step Statistical Process Control (SPC) performed classified as in analysis. Ishikawa diagram shows relation between considered consequence (small number passed...

The study represents a new approach of analyzing energy poverty using an intelligent method based on social factors. Energy one the most vital problems, especially in recent years, with serious implications social, economic, environmental, political, and health sphere. Identifying measuring parameters challenge not only national, but also regional level. This research to neural network application systems resource planning activities aim real socio-economic data. analyzed data are associated...

The aim of this paper is to propose a model for an energy management system (EnMS) in the hospitality industry line with ISO 50001 standard. new proposed model, specifically developed service organizations, was based on Plan–Do–Check–Act cycle and confirmed 280 hotels Western Balkans 6 (WB6) region. data were used investigate if hotel properties represent influential factor wider implementation EnMS requirements. standard, into sub-categories, including actual regulations legislation within...

This study aims to present the impact of disasters, such as COVID-19 pandemic, on possibility recovering from and mitigating impacts. The paper proposes a new emergency planning disaster recovery management model (EPDRM) which links ISO 31000:2018 (Risk Management) requirements with process approach. was validated through its application ISO-certified ISO-non-certified hotels. analysis performed by using an online questionnaire based requirements, where given questions were grouped into 14...

Buildings with indoor swimming pools have a large energy footprint. The source of major loss is the pool hall where air humidity increased by evaporation from water surface. This increases consumption for heating and ventilation hall, fresh supply heat demand heating. In this paper, mathematical model was made to assess demands an building. used created multi-zone building in TRNSYS software determine losses. Energy are analyzed different target temperatures. simulation showed that accounts...

The paper presents an application of the Finite Elements Method for stress and strain analysis hot water boiler structure. aim research was to investigate influence scale on thermal stresses strains structure boilers. Results show that maximum appear in zone pipe carrying wall first reversing chamber. This indicates most critical part are weld spots smoke pipes plate, which case significant deposits can lead cracks welds leakage from boiler. nonlinear effects were taken into account by...

Finance industry is considerably applying six sigma quality process with the aim of eliminating defects. Six a powerful system. Basically it measuring that longs for perfection (3,4 defects on 1.000.000 transactions). The very name this philosophy important. word Greek letter which represents standard deviation, term describes how distant data from average or middle. parts involved when one measures things company does right. This work shows example concept implementation crediting within...

This paper presents the results of multi-criteria ranking Danube water quality along its course through Serbia by using PROMETHEE/GAIA method. The was based on values parameters measured at eight measuring stations River in 2010. For purposes investigation, ten that indicate physical, chemical and microbiological characteristics were selected. These are also used WQI (Water Quality Index) methodology determining overall quality. show exit profile is better than entrance profile.

The paper aims at examining the possibilities of enhancing higher education process using quality tools, from perspective number passing exams, after introducing Bologna process. One goals is modernisation teaching by e-learning. Several tools are used, such as: Pareto analysis, Statistical Process Control and Ishikawa diagram. After defining defects (seven basic types waste) that have a negative influence on final evaluation how these can be eliminated, analysis done, which used for...

There are successful and less maintenance systems (MS).As a dynamic category, the success of function must be taken into consideration both for present day future.This is reason why it necessary to continuously evaluate, improve redesign MS.Business process modelling good methodology this purpose.A business model basically encompasses formal description concept system, evaluation methods improvement techniques.This paper presents MS by using statistical control in connection with performance...

Abstract Laboratories that are part of clinical centers faced with the inevitability their efficiency must be on a high level. Most biochemical laboratories automated, but they still underperforming. The best approach to increase or improve processes today is Lean Six Sigma methodology. This methodology extracts many benefits from automated processes. A lean process in laboratory focuses time cycle obtain results and reduce costs, both components at same time. provides take place without...

In the last twenty years, many companies have realized that demands of global market, including more demanding and receptive customers, set new standards for production flexibility. Gradual reduction mass production, characteristic a large number companies, has opened space introduction system which focuses exclusively on customer. The customer-oriented was created with idea process optimization would lead to relatively cheap product, delivered time best possible quality. Such is achieved by...
